BWAAAAAAAAAPPPPAPAPAPAPAPAAPA

so yeah i finished fitting the clutch after a lot of swearing last night and it feels good.

until this morning where it SHAT its gearbox oil all over the floor outside my work. NOT GOOD.

so off with drivers shaft again and pop the brand new seal out the box. bugger. i broke it...

but, those of you that listen to my moaning will know when i ordered shaft seals from nissan they ordered one correct one and one wrong one, then i ordered a new pair from greg @ Gspec. so the one nissan ordered was the one i fucked! happy days!

so autech is driving. making noise. pissing off neighbourinos
 
yeh my old sunny had one of them, was just the earlier sunny gti's had them, slightly later ones had the cast mani like almeras n stuff.

supposed to be pretty good for a stock mani
 
ok so me and rick were at the dyno today!

Story time.

arrived high spirited, would be happy with stock power (170) and stock + 50 for nitrous.

first run, brings it up and boots it to the wonderful figure of 141bhp. to the words from dunc "thats fucking shite!"

second run, boots it and lets it chirp off the limiter and reads 145bhp. still. not. good.

third run, up to 3k, hits the gas switch and the power flies up to 180bhp with a distinctive buzzing noise from the exhaust... DET. fuck.

fourth run i brought the timing back to 15* and done a run without gas, 161hp. so for some reason retarding the timing in this case gained power. thats really quite odd!

fifth run, nitrous brought in at 4250rpm, instant spike up at that point on the graph from 100hp to 155hp and continued climbing all the way to 198hp. with a maximum torque figure of around 190ft.lbs.

sixth and final run, brough the nitrous in earlier to give it a little more time to overcome lag and revved up to 6500 before that buzzing noise came back with a vengence. more det. netting 191hp

the next 20 minutes were spent discussing where to go from here. im advised to tighten up my plug gaps from 0.9 to about 0.7-0.6mm to give a better spark. where det presented itself the AFR reading was around 10:1. VERY rich, which dunc reckons is a result of the overfuelling quenching the plug.
